Adam5022 Posted September 10, 2021 Posted September 10, 2021 Hey guys, I'm needing a bit of help setting up my ano lens... I can't seem to get rid of this dark fade on the bottom and right side of the screen? I have tried tiny adjustments to the positioning of the lens, but this seems to be the best I can get there is also a very slight rainbow effect across the bottom, which doesn't really come out in the picture I'm running a sony vpl 590 with a Prismasonic P100R lens. Also in the chain is my oppo udp 203 and anthem 1140 There is also a pretty significant curve to the top of the picture, which is noticeable if you project straight lines, but not at all when watching a movie Any advice would be great, thanks in advance
Quark Posted September 10, 2021 Posted September 10, 2021 First of all, is the image a perfect rectangle without the lens in place? You need to start with this first. If you're having problems with this then post an image and I'll walk you through the alignment. There is no point in tweaking the lens if you don't have this right as it makes it impossible work out what is lens related. The vignetting at the bottom of the image and your photos of the lens suggest the lens is mounted too high - try lowering it a little. If that doesn't help, try less tilt on the lens - that is a slightly larger angle than I'm used to seeing. For the vignetting on the right, try moving the lens to the right a little (or projector to the left (if the latter you'll need to offset with some horizontal lens shift).
